Sicherheit & Vorschriften
| Treatment | There is no know antidote for PAHs. Exposure is usually handled with symptomatic treatment. (L10) |
|---|---|
| Gesundheitliche Auswirkungen | PAHs are carcinogens and have been associated with the increased risk of skin, respiratory tract, bladder, stomach, and kidney cancers. They may also cause reproductive effects and depress the immune system. (L10) |
| Expositionspfade | Oral (L10)inhalation (L10) |
| Toxizitätsübersicht | The ability of PAH's to bind to blood proteins such as albumin allows them to be transported throughout the body. Many PAH's induce the expression of cytochrome P450 enzymes, especially CYP1A1, CYP1A2, and CYP1B1, by binding to the aryl hydrocarbon receptor or glycine N-methyltransferase protein. These enzymes metabolize PAH's into their toxic intermediates. The reactive metabolites of PAHs (epoxide intermediates, dihydrodiols, phenols, quinones, and their various combinations) covalently bind to DNA and other cellular macromolecules, initiating mutagenesis and carcinogenesis. (L10, L23, A27, A32) |
| Signs and Symptoms | Acute exposure to PAHs causes irritation and inflammation of the skin and lung tissue. (A10) |
| Carcinogen Classification | Not listed by IARC. IARC has evaluated other PAHs (L2154). |
